Textbook Question
Chapter 11, Problem 37E
The boiling points, surface tension, and viscosities of water and several alcohol are as shown below:
| Boiling point (ºC) |
Surface tension (J/m2) | Viscosity (kg/m-s) |
|
| Water, H2o | 100 | 7.3 x 10-2 | 0.9 x 10-3 |
| Ethanol, CH3CH2OH | 78 | 2.3 X 10-2 | 1.1 X 10 -3 |
| Propanol, CH3CH2CH2CH2OH | 97 | 2.4 X 10-2 | 2.2 X 10-3 |
| n-Butanol, CH3CH2CH2CH2OH | 117 | 2.6 X 10-2 | 2.6 X 10-3 |
| Ethylene glycol, HOCH2CH2OH | 197 | 4.8 X 10-2 | 26 X 10-3 |
- From ethanol to propanol to n-butanol the boiling points, surface tension, and viscosities all increases. What is the reason for this increase?
- How do you explain the fact that propanol and ethylene glycol have similar molecule weight(60 versus 62 amu), yet the viscosity of ethylene glycol is more than 10times larger than propanol?
- How do you explain the fact that water has the highest surface tension but the lowest viscosity?

The following information is given for antimony, Sb , at 1 atm:
Boiling point = 1440.0°C
Heat of vaporization = cal/g
Melting point = 631.0°C
Heat of fusion = 38.5 cal/g
How many kcal of energy must be removed from a 44.9 g sample of liquid antimony in order to freeze it at its normal melting point of 631.0°C?
Energy removed = kcal
